Apparently I used the wrong terms. I should have used: NCQ (Native Command Queuing) PMP (Port Multiplier Protocol) CBS (Command Based Switching method for PMP) FBS (FIS Based Switching method for PMP) CBS obviously relies on NCQ. So the question is: - What is supported by which Allwinner hardware? - And what's implemented (active/inactive) in the drivers? And should we update?: https://ata.wiki.kernel.org/index.php/SATA_hardware_features Kr, Mike > > > > Regards, > > > > Hans -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
